Overview
The EL2252CME9053-EL is a dual comparator manufactured by Elantec, designed to replace traditional input buffer, attenuator, ECL comparator, and ECL to TTL translator circuit blocks in digital equipment. It operates with a supply voltage range of ±18V for single or dual configurations. Key electrical specifications include a maximum propagation delay of 9ns, an input hysteresis voltage of 60mV, and a maximum input offset voltage of 9mV at 15V. The device features a maximum input bias current of 16µA at 15V.
Feature Summary
- Dual channel configuration for high-speed comparison applications
- Integrated hysteresis to prevent output oscillation
- Replaces complex discrete ECL and TTL translation circuits
Applications
- Digital equipment signal processing
- ECL to TTL level translation
- High-speed voltage comparison
Procurement Notes
Verify the manufacturer part number EL2252CME9053-EL against official Elantec documentation to ensure authenticity. Confirm that the package type matches the required 20-SOIC specification if applicable, although some sources indicate 8-SOIC variants exist for similar models; cross-reference the specific suffix ME9053-EL for exact physical dimensions and pinout compatibility before finalizing procurement orders.
Selection Notes
Select this component when replacing legacy ECL comparator stages with integrated solutions. Ensure the system requires dual channels and can accommodate the specified 60mV hysteresis. Verify that the ±18V supply capability aligns with the target power rails and that the 9ns propagation delay meets the timing constraints of the digital application.
Part Context
This part belongs to the EL2252 series of linear comparators from Elantec, now associated with Renesas. The series is engineered to simplify digital circuit designs by integrating multiple functional blocks into a single IC, reducing board space and component count compared to discrete implementations.
Replacement Considerations
Check datasheets for direct substitutes within the EL2252 family. Verify pin compatibility and electrical parameters such as propagation delay and supply voltage range to ensure seamless integration without circuit redesign.
